Abstract:Clean energy is the core logical element of China's energy transformation strategy, which is closely related to science and technology innovation. Based on the data of science and technology innovation and clean energy industry from 2014 to 2018 in China, through the entropy method and the coupling coordination model, this paper finds that the coupling degree between science and technology innovation and clean energy is gradually strengthened and steadily improved, but it is not enough. As a result, China's energy transformation is still in the climbing stage of "slogan is more than actual action". It is necessary to continue to deepen the coupling degree between science and technology innovation and clean energy to make up for the lack of promoting energy transformation. Based on the empirical analysis, this paper studies and determines that the next stage of energy transformation with clean energy as the core will become more and more intense, and clean energy has a broad development prospect.
